To all 107mm it may concern.' y

Be it'known that I, CHARLES F. DATHAN, citizen of the Unitedv `States of America, residing at Chicago, in the county of Cook and State of Illinois, Vhave invented new and useful Improvements in Torpedo-Nets for Ships,r of which' the following is a speciication. l

This Y invention Vcomprehends generally improvements in that class of"v invention known as ships and more particularly has reference to la torpedo net for Ships. Y

It is the 'primaryvr aim and object of the Y present invention to provide a device of the `above character designed to surround that portion. of the hull 'of a vessel beneath Ythe water line to prevent torpedoes, mines, et cetera, from contacting with the hull of the Y VAs an kequally importantobject-the pres# ent invention recites the provision of a 'de'-V vic'e of the above mentioned character.

which is composedl of a plurality of sections constructed desirably of reticulated means, such as woven wire, so that the shield will not interfere-with the movement of the vessel in the water. j More particularly this invention includes a provision of improved supporting means Jfor maintaining the sections of the shield in spaced relation to the lsides ofthe'v hull when it Ais-'desired to veirijgiloyl vthe shield while said supporting means is also 'capable of being adjusted sol as to draw the-shield into close relation to the sides of the hull to permit lofdocking of the Ship when desired. Y

As Va'further improvement this invention embraces the provision `of improved means for connecting the sections of the shield to each other and to the, supporting means; and to also provideimproved meansV for swingingV the supportingv booms Vinto such a position that'tlieshield will be arranged in close relation Ato, the hull of the ship.

/ Ctlier ,improvements and novel details in the construction and*arrangementV of the various partsA of vtheA apparatus will be brought out` more in Vdetail in the description to follow, whichy fork a clear understanding of the' inventions'hould be considered in connection with' thev accompanying drawings forming apart hereof, and wherein is disclosed for the purpose of illustration a convenient and satisfactory ernbodiment of the. invention. It is to be noted in this connection that minor changes in the construction and arrangementl of parts may be made without departing from the principle of operation of the various parts.

The inventionis clearly. illustrated in the accompanying drawings, in Vwhich .Figure lis a side elevation of the invention. f

Fig. 2 is a fragmental longitudinal sectional detail thereof. i

- Fig-3 is a transverse section ofthe invention.

Fig. l is a top plan view of the invention, the' device being arranged in a close arrangement to the side of the hull, and Fig. 5 is an elevationaldetail illustrating the manner of connecting adjacent sections of the vshield together.

` Fig. 6 is a perspective detail of the outer extremity of one of the side booms.

Fig-7 lis a similar view of oneof the g bow or stern booms.4

Similar characters of reference are emi ployed in all of therabove described views, used to indicate corresponding parts.

Referring now, more particularly, to the accompanying drawings there is provided a ship 1 to the sides of whose hull at a point near the water lineare connected at'suitf able intervalsy attaching plates' 2 formed with outwardly projecting'horizontally arranged ears S'betwcen which are arranged the inner ends of booms tpivoted for horizontal swinging movement between the ears bvmeans of pintles 5. The outer ends of the vbooms 4 are Jformed with inwardly'extending intersecting horizontally and vertically arranged slots 6 and 7 for a purpose that will presently appear. .The clon of Vthehull beneath the water line a shield `desirably formed of `reticulated material such aswoven wire, while suitable supporting and connecting cables 18 are trained through the adjacent ends of the sections 15 and 16 and Y15 and 17 for connecting the the cable 1S are trained through the verti-l cal slots 7 in the; outer ends of booms 4 whileextreme upper terminals are cion-v nectedf to suitable posts 19 and in'addition to connecting all sections of the shield serve `to brace the booms 4. Other cables 20 serve to connect t-he outer side edges of the' see# tions 16fand .17 to' each otherY while ythe upper portions of thecables' are trained throughY the vertical slots 13 and the ends of the booms S andl are finally connected to posts 21 carriedby the bow and stern of the ship'. 'i'

Cooperating n another cable 22 which has'one end-connected tothe post 21 on the bow'of the vessel and extends downwardly and is trained through the horizontalislot'in'the adjacent boom 4; This cable'is'also trained-through lthe upper Vedges of these'ctionsY 15V and 16 and through thehoriZontal'slots in. they booms' 4 and the vrear boom 8 as itis arranged about thehull kand is anchored on the post 2-1`onthe bow.

By the provision of this Cable 22 it is-'apparent that subsequent tothe raising ofthe rear cable 20 with a view to raising the rear lboorh 8 theends'of the-cable22 are pulled so as to draw thesections v15 and 16 in close relation with .the adj aeent portions'of the hullf to consequently permit the dock-ing `of the ship when desired. .Cooperating with the front cable20 is-another cablep23 ;oneend of which is connected to a post l24 rearwardly of the forward post 19.- This cable istrained through a horizontal slot in the frontbooms I 4'and in the front-boom S tand also through the upperiedge ofthe section -17 ofthe shield preparatory to being connected at` its oppositeend to a post 25, which is disposed opposite to the post 24. y When the ends of the cable 23 a'repulled,` of course,- subsequent to the pulling of the fron-t cable`=20 upwardly the section 17will be drawn in close -relation to the adjacent portion ofthe hull'of the ship. In order to assure of the maintenance of the sectionsofthe shield in spaced relation to the keel as wellas the bow and stern of the hull a relatively-stiff curved orsi-nuous wire 26 is; secured to the keel andthe stern and bow ofthe. ship.:` v A Y In use, Whenit isdesired-to arrange the shield in close relation with the sides lofthe hull of thelshipl, the. front and rear cables 2O are pulled. upwardly toV raisethe' corre! spondingbooms 8. Subsequent to this action The upper portions of designed to 'slip through the slot in the ends withithe cables 18V and 20 is`r the endsof cables 22 are drawn inwardly and fastened about the posts 21 on the bow which draws the sections 15 and 16 toward the adjacent portions of the hulll and also swings the booms 4 laterally" so that they will be 70 Vheldin.proximity to the sides of the hull.

Finally the ends of the cable 23 are tightened to draw the forward section 17 of theshield inclose relation to the hull the cable being of the forward booms 4. Y When held in the position described the ship may be docked. To extend 'the shield it is-o'nly' necessary to releasethe'cab-les 22', 23 and*20,fowingto the weight thereof the :shieldwill swingdownwardly and outwardlyl to assume the position as indicated in Figs. 1 and 3 of the drawings.- .Iny view of the foregoingd'escription a fur# ther detail description of the operation of the invention is entirely unnecessary.-V It is Ylikewise believed that the advantages of the in-v ventionwill-bereadily apparent;

Having thusfullyv zdeseribedthe invention whatl claimand desireto secure by Letters Patent isff i 1s The combinationwith the hull of the ship ofvertieally swinging booms on the bow and sternthereofj laterally swinging booms on the sides! ofthe hullya; sectional vshield. composed of a plurality of reticulated cally swingingbooms andhavingtheir upper terminals connectedto thej'bow and stern 105 of the hull and supporting` cables'trained j through the ends of the booms and the. upper nected to the hull.
